Abstract
PURPOSE: To effectively provide a branched portion in a base pipe, the base pipe hole is treated by the self turn and orbital motion of a rotating roller.
CONSTITUTION: A base pipe 1 having a base hole 3 is fixed and a rotary roller 9 is positioned into the base hole 3 to be set by a support fixture 11. While controlling the momentum of the self turning, orbital motion, and axial movement of the rotary roller 9, the base hole is worked maily by bending so as to form a branched portion 2 having a desired diameter and height. Thus, a branched pipe is effectively manufactured in a small work number.
